All the opals i sell are professionally cut and polished by me. I have been in the wholesale opal business for over 15 years. Selling to exporters and retail shops. You are guaranteed to get the best possible quality for the best possible price when buying from me.All the opals that I sell are solid Lightning Ridge opals that are NOT treated in any way. Quoting a customer: "I think you are the ONLY decent black opal seller on the entire internet. Opals
are so rare and hard to come by, good black opals, unlike diamonds
where you can buy a fine diamond any day of the week for any amount of
money, but fine black opals, whether you have the money or not,
sometimes you might have to wait months for a real nice one to pop up
online for sale, which is because they are only found in one place in
the world, Australia."
